7217 CDGC/P4A 150 mm 85 mm 28 mm Frequently Asked Questions about 7217 CDGC/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the 7217 CDGC/P4A Super-precision Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7217 CDGC/P4A with a precision bore diameter (d) of 85 mm, an outside diameter (D) of 150 mm, and a nominal ring width (B) of 28 mm. This configuration yields an effective cross-sectional wall thickness of 32.5 mm and an envelope ratio (D/d) of 1.76, delivering compact rigidity for OEM machinery housings.
Every production batch of CHG Bearing 7217 CDGC/P4A Super-precision Angular Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
When fitting 7217 CDGC/P4A over a 85 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
